From MFG Calcs data: Batteries and storage cells

U.S. imports of batteries and storage cells (headings 8506, 8507) came to $27.08B in 2025, with $4.34B in calculated duty: an effective duty of 16.0%, every duty included.

Effective duty in Sep 2026: 14.0%, against 22.2% in Sep 2025.

Largest sources in 2025: China $12.23B at 24.0% effective duty; South Korea $3.88B at 7.9% effective duty; Japan $3.63B at 12.2% effective duty; Mexico $1.71B at 1.5% effective duty; Vietnam $973M at 13.5% effective duty.

These are family totals from U.S. import statistics published through USITC DataWeb, not this heading's rate alone; effective duty is calculated duty as a share of customs value, an estimate, not a ruling.

About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
